An efficient formulation design based on thermodynamic modeling

Thermodynamic models are increasingly recognized as essential part in pharmaceutical formulation development of
“small-molecule” drugs. However, modeling of highly complex (bio-)pharmaceuticals (e.g., monoclonal antibodies) remains
a challenging task. Within this work, we developed a modeling approach to access protein-protein and protein-excipient
interactions for pharmaceutical proteins in the presence of different excipients using the ePC-SAFT equation of state. This
approach gives access to protein phase behavior in these complex solutions and allows to gain a mechanistic understanding
on the complex interactions involved enabling an optimized formulation development.
